IMPROVEMENT IN RULERS.

Specification forming part of Letters Patent N0. 205,795, dated July 9,1378; application filed November 28, 1877. I

To all whom it may concern:

Be it known that I, JOHN W. GREEN, of Pontiac, in the county of Oakland,in the State of Michigan, but temporarily residing in the city ofW'ashington, in the District of O0- lumbia, have invented a new anduseful Improvement in Rulers for Drawing Ornamental Lines, which isfully described in this specification.

The principal object of this invention is to add artistic beauty tocommercial papers, and to documents which, from their nature, wouldalways be prized by the owner, by making waved or corrugated linesacross the paper.

The invention consists in a ruler, or any other similar device fordrawing purposes, having an indented or corrugated edge, curved orangular, for the drawing of waved lines or waved lines in series, or asuccession of other than straight lines, for the ornamentation ofcommercial and other papers.

In the drawing, Figure 1 shows the ruler, and Fig. 2 a hand in the actof drawing waved lines. Figs. 3 and 4 are modifications.

The ruler A may be made of any material, gutta-percha being preferable.The notches B need no description, as an inspection of the drawing isall that is necessary to give any person an idea of the invention.

The modifications O D are for drawing more prominent lines than can bedrawn over the notches B. Lines to I) c 17, produced by this ruler, arealso shown in the drawing.

Although this invention is shown as applied to a straight ruler, it isalso the intention to apply it to draftsmens curves of different formsfor the purposes of ornamentation in drawin One surface or edge may beleft plain, in the usual manner, if desired, and the indentations may beof various designs, as shown by the modifications, and which may beinterchangeable.

The notches may continue the whole length of the ruler, or the ruler maybe made with alternating distances of straight and notched edge.

It is obvious that the invention may be applied to a round ruler as wellas to a fiat ruler.

The pen patented to me August 14, 1877, No. 194,038, is speciallyadapted for drawing lines with this ruler.

In the preparation of deeds, policies of in.- surance, and commissionsin the diplomatic, civil, military, and naval branches of thegovernment, where blank spaces need to be filled and where artisticbeauty is always desirable, especially when it can be had at no loss oftime, this ruler will be of service. A person can draw a waved lineacross the paper as quick as he can draw a straight line, and, with afew minutesof practice, he can draw waved lines in series, or he can sojoin two lines as to give them the appearance of a cord drawn upon thepaper. He would need but a minute or two to border the fly-leaf of abook in ornamental designs, and where difi'ercut-colored inks are usedsuch designs may be made of very attractive appearance.

In the filling up of checks or drafts a use of this ruler will preventtheir alteration, for, by drawing a heavy line, the sudden motion orslipping 0f the pen causes it to penetrate the paper, making it verydifficult to erase the line drawn. It would be no less difficult toerase a series of lighter lines, because it would be nearly impossibleto reproduce them, or to attempt to do so, without detection.

I claim as new and desire to secure by Letters Patent A ruler or othersimilar device for drawing lines, having a notched edge, substantiallyas described.

In witness whereof I hereunto subscribe my name in presence of twoattesting witnesses this-.Jth day of November, 1877.
